Here are some recent space-related stories of interest.

—CNBC: “SpaceX Rival Launches Rocket in Historic First, Says Industry is ‘Desperate’ For More”

German rocket maker Isar Aerospace successfully reached orbit for the first time over the weekend, marking a milestone for Europe’s commercial space industry as the company looks to ramp up launches to meet what it says is booming demand. The Munich-based company’s Spectrum rocket reached orbit on Saturday and successfully deployed its payloads in low Earth orbit, an achievement that came on only its second test flight. Chief Commercial Officer Stella Guillen told CNBC on Monday that the company was now focused on scaling production, saying the space industry was “desperate” for additional launch capacity and that Isar had a pipeline worth more than 10 billion euros ($11.6 billion).

—Royal Astronomical Society: “‘Fingerprints’ Inside the Sun Could Reveal If It Once Swallowed a Planet“

It is thought the Sun may have engulfed a super-Earth-sized planet early in its history. Now a new study has gone a step further by suggesting that such an event may have left behind detectable clues inside our star which could still be visible today. This idea of a measurable signature or ‘fingerprints’ in the present-day solar interior was explored by research published today in Monthly Notices of the Royal Astronomical Society. Professor Mutlu Yildiz, of Ege University in Turkey, said: “Our new study suggests that a planet several times more massive than Earth may have fallen into the young Sun and left a lasting chemical imprint deep inside it.

—Physics World: “Moon’s Water Reserves Insufficient to Sustain a Lunar City, Astronomers Find“

Some countries and even wealthy individuals are setting their sights on the Moon with ambitious plans to create a lunar colony. That would require a lot of resources launched from Earth, but how much water and power would be required to keep a lunar city going?…Even assuming one billion tonnes of water on the Moon, if nothing was recycled then a city of a million would last only a few years while a population of 100 000 would run for 20 years before running dry. Even when recycling the water with an efficiency of 98% – as performed on the International Space Station – a city of a million would only have enough water for around a century.

The solar eclipse is almost here. The map above from The Arctic Portal shows you the path of tomorrow’s eclipse, which reaches its maximum over Iceland.

NASA also has a number of handy maps for past and future eclipses at its Eclipse Data site, though it is a bit technical. The graphic for tomorrow’s eclipse is shown below.

Enjoy the view…and mind your eyes.

Space Stories: Renaming Wallops, Powering Voyager 2, and Catching the Solar Eclipse

Here are some recent space-related stories of interest.

—WBOC News: “Push to Rename NASA Wallops Facility Sparks Debate Over Eastern Shore History“

A request to honor one of the Eastern Shore’s most accomplished aerospace leaders is facing growing opposition from people who say changing the Wallops name could erase an important piece of local history. The Accomack County Board of Supervisors unanimously approved a resolution July 15 asking NASA to rename the Wallops Flight Facility in honor of A. Thomas Young, a Wachapreague native who built a decades-long career in the nation’s space program and aerospace industry.

—NASA: “NASA Engineers Help Prolong Voyager 2’s Science Mission“

Engineers at NASA’s Jet Propulsion Laboratory have successfully freed up power on Voyager 2, extending how long the spacecraft can continue to do science. Nicknamed the “Big Bang,” the effort involved simultaneously turning off certain powered devices and substituting them with lower-power alternatives while ensuring the spacecraft remains warm enough to operate.

—Sky & Telescope: “Where to See the August 12th Solar Eclipse Online“

On August 12, 2026, millions will witness a total solar eclipse that crosses the north Atlantic and parts of Europe. The path of totality passes over Greenland, Iceland, Spain, and a corner of Portugal. Other parts of Europe and North America will see a partial solar eclipse. If you are in the path of totality or if you will be able to see the partial eclipse, head outside to see it for yourself! (Make sure you bring a good pair of eclipse glasses to protect your eyes.) But if you’re not in the path, or if clouds obscure your view, there are plenty of options for viewing this celestial spectacle online. What’s more, each broadcast listed here has its own roster of experts speaking about different aspects of the eclipse and the science around it.

Pic of the Week: Surface of the Sun

This week’s image is from the U.S. National Science Foundation’s (NSF) National Solar Observatory (NSO). It shows the highest resolution image ever captured of the Sun’s surface. The image was captured by the Inouye Solar Telescope located in Maui, Hawaii.

Here is more from the NSF about this image:

Using the world’s most powerful solar telescope, the NSF Daniel K. Inouye Solar Telescope near the summit of Maui’s Haleakalā, combined with computer simulations, an international team of scientists from the NSO, NSF NCAR High Altitude Observatory (HAO), and the Max Planck Institute for Solar System Research (MPS) found the signature of Kelvin-Helmholtz instability (KHI), tiny swirling patterns like small whirlpools, on the Sun’s surface. Researchers suggest that KHI might be a key reason why the Sun’s outer atmosphere gets so hot, and why magnetic energy builds up and moves around on the Sun. Magnetic energy fuels solar flares and eruptions—the kind of solar activity that can send bursts of energy toward Earth and affect satellites, power grids, and other technology. The discovery opens a new window into the fundamental physics of the Sun and other stars while underscoring the unmatched capabilities of the Inouye Solar Telescope.
